To develop and evaluate biodegradable, porous silk-polyethylene oxide (PEO) microtubes as scaffolds for endothelial cell growth and microvascular tissue regeneration.
Fabricated porous microtubes from blends of silk fibroin and PEO across varying concentrations, including a 13% silk and 1% PEO formulation.
Assessed vascular endothelial cell attachment, metabolic activity, and cell proliferation on the microtubes over a 14-day culture period.
Characterized structural and biomechanical properties, including pore diameter, scaffold porosity, crystallinity, elastic modulus, and degradation rates.
All silk-based microtubes supported endothelial cell proliferation over 14 days, with cell attachment increasing in proportion to scaffold porosity.
PEO-blended silk tubes exhibited a higher elastic modulus than PEO-free tubes while maintaining equivalent crystallinity.
The 13% silk and 1% PEO formulation achieved the highest average pore diameter (20 μm), highest cell attachment, and most rapid degradation profile.
